Checkweigher
SameGram automatic checkweighers verify every carton, bottle, pouch and tray in real time, catching underweight, overweight and missing-item errors before they leave the line. Each system is built to your product, speed and reject requirements, and drops into your existing conveyor with minimal changeover. High-resolution load cells hold tight net-content tolerances and reduce give-away across long production runs. High-speed inline weighing and sorting keep pace with filling and packaging lines without bottlenecking. Calibrated to international accuracy classes and built to recognized electrical safety standards for export markets. Modular conveyor modules, rejecters and line controllers connect to existing PLC and MES environments.
In-line checkweighing is suitable for quality control at the end of various production lines

Real SameGram checkweigher deployments across beverage, logistics and high-speed packaging lines. Inline weight verification replaced manual sampling and removed underweight shipments from a card-packaging line. A wet-environment checkweigher with SUS316 contact parts controlled fill weight and cut give-away on a bottling line. Parallel lanes lifted throughput for efficient package inspection while keeping per-lane accuracy within tolerance. Guides on checkweigher accuracy, standards, reject systems and integration written by the SameGram engineering team. The core principles of inline weight verification and where checkweighers fit on a packaging line. How payback from reduced give-away and recalls typically lands between 6 and 18 months. What the OIML R51 accuracy classes mean for compliant net-content control and integration. Air-blow, pusher, drop and diverter reject options matched to product and line speed. Why SUS316 stainless contact parts matter for washdown and corrosive environments. Combined weigh-price-labeling for high-volume distribution and traceability. Depending on model and product, standard resolution reaches plus or minus 0.1 g to plus or minus 0.5 g, calibrated to the relevant OIML R51 class for your market. Yes. Checkweigher + metal detector combos share one frame and HMI to save footprint, and we support inline code spraying, labeling and MES/ERP data exchange. It weighs every packed or unpacked item in motion, classifies it against preset weight zones, then rejects, sorts or diverts off-spec products automatically — catching underweight, overweight or missing items. Air-blow, pneumatic pusher, drop-through and diverter arms are offered, chosen by product shape, weight and line speed to protect good units. Built to recognized electrical safety standards. Accuracy classes for legal net-content control. Quality-managed design and manufacturing. Application engineering and spare parts worldwide. Send your product specs, line speed and target accuracy. We will recommend a checkweigher configuration and reject method, then share a layout and quote.
